Bowing to what he called an “unforgiving climate,” Robert Sarver said Wednesday that he planned to sell the Phoenix Suns and Mercury amid public pressure after an N.B.A. investigation found that he had mistreated team employees for years.

It was a swift turnabout for Sarver, who seemed determined to hold onto his stakes in both basketball franchises after the N.B.A. last week fined him $10 million and suspended him from team operations for one year. According to the investigation’s report, Sarver had engaged in more than a decade of workplace misconduct, including using racial slurs, making sexual remarks and treating women inequitably.

But following the punitive measures, Sarver — and the N.B.A. — faced mounting public pressure to levy a harsher punishment for behavior N.B.A. Commissioner Adam Silver had described as “beyond the pale.”
In a statement Wednesday, Sarver said his one-year suspension would have given him time to “make amends and remove my personal controversy” from the teams that he owns.
